chain sprocket single-phase Induction Motors
The single-phase motor operates beneath the same principle as the polyphase motor, except that the rotating magnetic field effect produced by the stator will not exist until running rpm is reached. Since no beginning torque is available, a design system is included to start the motor. They are the various designations:
Torque-Speed Curves of Different Single-Phase Induction Motors
Shaded-pole: Have only one main winding and no start winding. This configuration causes a shift of the used magnetic field in romantic relationship to the rotor, creating stating torque. Applications include fans and small appliances.
Split-Phase (induction start motor)
Has two models of stator windings. The “start” windings sit 90 degrees to the “run” windings and shift the magnetic field of the stator, inducing starting torque. Applications include little grinders, small supporters, and blowers.
Capacitor-Start
The most common single-phase motor used in industrial applications. It is a altered split-stage electric motor with a capacitor in series with the beginning winding to supply a start boost. Program include small conveyors, huge blowers, pumps, and direct-drives.
Permanent-Split-Capacitor (PSC)
Uses identical primary and auxiliary windings with a capacitor to provide starting torque. They will be the most reliable single-phase engine because no centrifugal beginning switch is necessary. Applications include supporters and pumps in HVAC and refrigeration industries.
